The AFE Momentum Intake System with Pro Dry S Filter is engineered to enhance airflow and optimize performance for the 2021-2023 Acura TLX models. Featuring a unique filter-to-housing interface, this system allows for the largest possible 9-inch tall radial flow air filter, providing increased surface area for improved filtration and longer service intervals. The oil-free Pro Dry S media incorporates three layers of synthetic filtration, offering high dust-holding capacity and efficient air cleaning without the need for oils. Its inverted top design maximizes filter surface area, ensuring consistent airflow and filtration efficiency under demanding driving conditions. Constructed from heat-resistant cross-linked polyethylene (XLPE), the sealed one-piece housing is durable and lightweight, designed for quick installation with fewer parts thanks to its innovative patent-pending interface. A clear sight window facilitates easy inspection without system disassembly, while the auxiliary air inlet allows additional airflow from the engine compartment or can be sealed when not in use. The included computer-designed, dyno-tuned intake tube is crafted from XLPE for heat soak resistance and durability, ensuring maximum power gains while maintaining a perfect fit. An extension harness is provided to enable seamless relocation of the Mass Air Flow (MAF) sensor, simplifying installation and customization. Premium stainless-steel clamps and a silicone coupling enhance system strength and longevity. Designed for ease of installation and optimized for street use, the AFE Momentum Intake System offers a significant upgrade in airflow and engine responsiveness for your Acura TLX.
